Thus the three basic bipolar transistor circuit configurations have equivalents ... If you’ve ever used a varicap diode, the capacitance between the two sides of this variable-width zone is ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

The VCO (Voltage Controlled Oscillator) in this IC uses a Colpitts oscillator circuit. The variable-capacitance (varicap) diode and feedback capacitors for the tuning have also been integrated on this ...

When looking across the discrete components in your electronic armory, it is easy to overlook the humble diode. After all ... you’d find in tunnel, Gunn, varicap, Zener, and avalanche diodes ...

In essence, the four-layer diode was the first integrated circuit since it did the work of two transistors, two resistors, and a diode -- all in a single crystal. Unfortunately, they were so ...
